Quick Summary

Trisha Mahajan, an Indian-origin teenager, developed a mobile keyboard at age 13 that identifies offensive messages before posting, and has since created a non-profit organization called ReThink against cyberbullying. The app, which interrupts users before sending potentially hurtful messages, was tested in an experiment with teenagers showing a significant decrease in willingness to send aggressive content after being prompted to reconsider. According to the article, the organization's efforts have resulted in over 500,000 downloads of the app and work with over 5 million students across 134 countries. The non-profit has received recognition from prominent figures, including an invitation to the White House and a TED Talk, as well as praise from Prince Harry and Meghan Markle.

Story summary

Trisha Mahajan, an Indian-origin teenager who was 13 years old in 2013, developed a mobile keyword that identified offensive messages before posting. This technology would prompt users to reconsider sending hurtful messages, and a study by The Harvard Crimson found that it was effective, with over 93% of instances where users were prompted to reconsider resulting in them not sending the message. Mahajan's work was inspired by her own experience with cyberbullying and the tragic story of Rebecca Sedwick, who died by suicide after facing relentless online attacks. At the time, most prevention methods relied on victims blocking or reporting attackers, but Mahajan's technology aimed to address the problem proactively. She has since taken her dream further by creating a non-profit organization against cyberbullying, which has received support from around the globe, including Prince Harry and Meghan Markle.
